Up for auction is an outside mold which is for a rather large guitar.  It is made of laminated wood, five sections (one section stacked upon another), glued together.  It is very sturdy.  I bought this off ebay about a year ago, but I then decided I wanted to make an OM- (Martin) size (a smaller) guitar.  This form would work well for a blues guitar.  I will give dimensions for the outside of this form even though those for the inside are more critical.  End to end:  19 and 15/16ths outside; 18 and 3/16ths inside.  Upper Bout:  13 and 9/16ths outside; 11 and 11/16ths inside.  Lower Bout:  16 and 7/8ths outside; 15 and 1/16 inside.  Sold "as is."  This sale is for the USA only.  Shipping price is $12.00.  Happy Bidding!
